Abstract
1H spin–lattice and spin–spin NMR relaxation times change markedly during the aging of nitrile rubber elastomers. NMR microimaging reveals heterogeneous changes in the aged samples. Aging proceeds mainly via additional chain cross-linking, and scission of the polymer chains does not appear to contribute. T1 imaging shows that there is no spatial distribution of spin–lattice relaxation times.
